I could care less if Mexico makes Mexicans pay higher taxes. This tariff was retaliatory and was done to force the US to lose revenue and force the US into accepting Mexican trucks.
If Mexico wants to punish the U.S. by punishing Mexicans by taxing them harder, I would just stand there pointing and laughing, but hey, that’s just me. The only people having money taxed out of their pockets are Mexicans. American have a 100% effective tax avoidance trick - don’t sell anything on the tariff list to Mexico. Sell it in some other country. No revenue loss.
Notice how effective the retaliation was. If it wasn’t mentioned in the article no one would notice it, including you.
